: System Notes

As a 2U Twin

2

conguration, the SuperServer 2028TP-HTR/HTTR/HTFR is a unique

server system. With four system boards incorporated into a single chassis acting as

four separate nodes, there are several points you should keep in mind.

Nodes

Each of the four serverboards act as a separate node in the system. As independent

nodes, each may be powered off and on without affecting the others. In addition,

each node is a hot-swappable unit that may be removed from the rear of the chassis.

The nodes are connected to the server backplane by means of an adapter card.

Note: A guide pin is located between the upper and lower nodes on the inner chassis

wall. This guide pin also acts as a “stop” when a node is fully installed. If too much

force is used when inserting a node this pin may break off. Take care to slowly slide

a node in until you hear the “click” of the locking tab seating itself.

System Power

Dual 2000 Watt power supplies are used to provide the power for all four

serverboards. Each serverboard however, can be shut down independently of the

other with the power button on its own control panel.

SATA Backplane/Drives

As a system, the SuperServer 2028TP-HTR/HTTR/HTFR supports the use of 24

SATA drives. A single SATA backplane works to apply system-based control for

power and fan speed functions, yet at the same time logically connects a set of

six SATA drives to each serverboard. Consequently, RAID setup is limited to a

six-drive scheme (RAID cannot be spread across all 24 drives). See the Drive

Bay Installation/Removal section in Chapter 6 for the logical hard drive and node

conguration.

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your SuperServer

2028TP-HTR/HTTR/HTFR up and running. Following these steps in the order

given should enable you to have the system operational within a minimum amount

of time. This quick setup assumes that your system has come to you with the

processors and memory preinstalled. If your system is not already fully integrated

with a serverboard, processors, system memory etc., please turn to the chapter or

section noted in each step for details on installing specic components.

2-2 Unpacking the System

You should inspect the box the 2028TP-HTR/HTTR/HTFR server was shipped in

and note if it was damaged in any way. If the server itself shows damage you should

le a damage claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold the 2028TP-HTR/HTTR/HTFR

server. It should be situated in a clean, dust-free area that is well ventilated. Avoid

areas where heat, electrical noise and electromagnetic elds are generated. You

will also need it placed near a grounded power outlet. Read the Rack and Server

Precautions in the next section.

2-3 Preparing for Setup

The box the SuperServer 2028TP-HTR/HTTR/HTFR was shipped in should include

two sets of rail assemblies, two rail mounting brackets and the mounting screws you

will need to install the system into the rack. Follow the steps in the order given to

complete the installation process in a minimum amount of time. Please read this

section in its entirety before you begin the installation procedure outlined in the

sections that follow.

2-2

SUPERSERVER 2028TP-HTR/HTTR/HTFR USER'S MANUAL

Choosing a Setup Location

•Leave enough clearance in front of the rack to enable you to open the front door

completely (~25 inches) and approximately 30 inches of clearance in the back

of the rack to allow for sufcient airow and ease in servicing.

•This product is for installation only in a Restricted Access Location (dedicated

equipment rooms, service closets and the like).

•This product is not suitable for use with visual display work place devices

acccording to §2 of the the German Ordinance for Work with Visual Display Units.

2-4 Warnings and Precautions

Rack Precautions

•Ensure that the leveling jacks on the bottom of the rack are fully extended to

the oor with the full weight of the rack resting on them.

•In single rack installation, stabilizers should be attached to the rack. In multiple

rack installations, the racks should be coupled together.

•Always make sure the rack is stable before extending a component from the

rack.

•You should extend only one component at a time - extending two or more

simultaneously may cause the rack to become unstable.

Server Precautions

•Review the electrical and general safety precautions in Chapter 4.

•Determine the placement of each component in the rack before you install the

rails.

•Install the heaviest server components on the bottom of the rack rst, and then

work up.

•Use a regulating uninterruptible power supply (UPS) to protect the server from

power surges, voltage spikes and to keep your system operating in case of a

power failure.

•Allow any hot plug drives and power supply modules to cool before touching

them.

•Always keep the rack's front door and all panels and components on the servers

closed when not servicing to maintain proper cooling.
